The shaft 62 has a square lower portion 63 which sldably engages the Worm Wheel 54 having and the bottom member I4. The latter 1s bolted the projections 65 which are cylindrical on their to the base plate 20 by the bolt l '5- A' threaded outer faces. A journal bracket 66 is indicated Stem I6 extends through th? top member.' 370i 50 with the annular DGI-tion 61 and the upper polthe bracket H2, and 1s adjustably clampedlin tion 68. The annular portion 61 engages the propla@ by the nuts l" and 'm The Spring "25 jection es on tbe bottom side of the worm whee1 is Suspended from the lower end 0f the Stemlli! 64. A journal bracket 69 is indicated with the and a 100D |2| iS SPJWH at the lower end of the gg annular portion 10. The latter engages the prosaid spring. A pin |22 with the nut |23 extends 55 |2| of the spring |20.

Supporting legs |25 extend up from the supporting plate 20, An electric motor |30 in this instance, is supported on the supporting legs |25. The armature shaft |3| of the electric motor has fastened thereto the pulley |32. A belt |33 connects the pulleys 39 and 32.

A journal bracket is supported upon the supporting plate 20 and is fastened thereto by the screw bolts |4l. A shaft |45 to be controlled is indicated with its journal end |46 supported in the journal bracket |40. A pulley |48 is fastened to the journal end |46, and a belt |50 connects the pulleys 40 and |48.

To utilize the shaft controlling apparatus the.

electric motor |30 is energized, in the usual way by means not shown. The main shaft 38 turns with the rotations of the armature shaft |3I, by means of the belt |33 that connects the pulleys 39 and |32. The crank 44 revolves with the rotations of the main shaft 38. The arm |00 revolves with the crank 44 and thereby the controlling shaft 98 is turned. 'I'he arm |05 with its controlling Weight |08 revolves and swings down the controlling beam 84 against the tension of the spring |20 which latter swings said beam upwardly after the arm |05 begins to swing upwardly. By means of the oscillations of the controlling beam 84 and the coaction of the arm |05 and the spring |20, the controlling shaft 98 has imparted thereto a uniform rotation, as would result from a heavy fly wheel. It will be noted that the controlling weight |08 can be clamped on the arm |05 at different distances l.from the axis of the controlling shaft 98, and

-I thereby vary the moment of said weight with respect to the axis of the shaft 98. By this means the effect produced by the Weight against the tension of the spring |20 can be varied.

The angle through which the beam 84 oscillates is controlled by the bumper discs 14 and 80, each of which can be positioned different distances from said beam 84.

'I'he uniform rotation of the controlling shaft 98 is transmitted to the main shaft 38, and the latter shaft transmits its uniform rotation to the shaft |45.

The controlling shaft 98 may be rotated by turning the pulley |02, by means not shown instead of rotating it by means of the main shaft 38, and in such a case the rotations of the shaft 98 will be transmitted to the shaft 38.

Various modifications may be made inthe invention and the present exemplification is to bev taken as illustrative and not limitative thereof.
